Who can beat Azashiro Kenpachi

History

Soya Azashiro (痣城宗谷, Azashiro Soya), otherwise known as Kenpachi Azashiro (痣城剣八, Azashiro Kenpachi), is the eighth generation holder of the title of Kenpachi and is also the eighth Captain of the Eleventh Division. He obtained this title after defeating Kenpachi Kuruyashiki, the previous Kenpachi. Due to his treacherous betrayal of the Soul Society, he was apprehended by the Royal Guard and sentenced to the Mūken. Azashiro was eventually broken out of Mūken by Kamui and is now a member of the Tenka clan.

Zanpakuto

The name of Azashiro's Zanpakutō is currently unknown. Its sealed form is also unknown because it is never seen on his person. Shunsui Kyōraku stated that Azashiro had never revealed his Zanpakutō in person, and when he was confronted about this by Central 46, he stated that "I've already shown it." Kyōraku also noted that people would say "to explain this in a specific manner, he, indeed, kept his Zanpakutō on him, but it was not seen by our eyes." The spirit of Azashiro's Zanpakutō has shown herself to be a woman with purple hair styled in a manner befitting a traditional royal princess, along with a gold necklace with several strands hanging down from the front. Two dark purple sashes go around her cheeks, covering up both of her eyes, in an x-shaped manner. She wears a light purple kimono with two dark sashes running up and down both edges of the kimono, both of which are dark purple in color with a gold diamond design. The kimono is left open and loose to reveal her large ample bosom. It is kept tied together by a pink obi with a flowery design in a ribbon. From what has been seen, the spirit of Azashiro's Zanpakutō is rather crude and sadistic, in comparison to her level-headed and indifferent master. Even when speaking with Sōsuke Aizen, a dangerous criminal of immense strength, she only spoke in sarcastic and mocking remarks about the former. She suggested that Azashiro steal the Hōgyoku from Aizen by tearing him apart in cold blood, from his toes to the blood vessels behind his eyes. In addition, she appears to be deeply infatuated with her master, always finding an excuse to whirl her arms around him in a seductive manner.

Bankai

Uro Zakuro (雨露石榴, "Rain and Dew Pomegranate") is the name of Azashiro's Bankai form. It has been heavily rumored that his Zanpakutō remains in a constant release of Bankai. In addition, Shunsui Kyōraku noted that Azashiro was able to obtain his title by killing Kenpachi Kuruyashiki in a single attack using his Bankai, implying that its strength is unrealistic. There does not seem to be visible form of the Bankai on Azashiro's person.

The power of Azashiro's Bankai is known as Yūgō (融合, "fusion/merge"). As the name implies, it allows Azashiro to merge his being with other substances, whether they be living or nonliving; organic or inorganic. Likewise, he can merge two or more substances together as well. That which he fuses with or to is not limited to just physical substances. Such things as the five senses can also be subject to this ability; ideally, not just physical, but anything mental and spiritual are also subject to influence. One such example is that he could merge his senses to the air surrounding the Seireitei, allowing him to know, see, and hear everything that occurred within the Seireitei's walls. Using this same ability appears to allow him to outmaneuver Aizen's Kyōka Suigetsu, which has the power of complete hypnosis, to the point that Aizen himself claimed that Kyōka Suigetsu would be rendered useless against Azashiro. As a defensive measure, Azashiro can merge with the air so that all enemy attacks are unable to make contact with him. He can also use this technique to teleport vast distances effortlessly, appearing akin to that of spacetime manipulation. The degree to which Uro Zakuro allows him to merge his being with desired targets is vast, such that some instances of this ability can be demonstrated as though Azashiro had not done anything whatsoever, or rather the effect that has been put into motion is not noticeable, whereas in other circumstances, the merging power becomes visibly evident once the effect is put into action. Azashiro is able to produce a blade/razor-like effect in the air around him, allowing him to kill his opponents without a single motion nor a glance, although the specifics at which this power is tied into his "fusion" ability is not yet clear.

Seitai Yūgō (生体融合, "living body fusion"): One of his Bankai's ultimate technique, Azashiro used this ability to kill Kuruyashiki in a single move. While the specifics of the technique have not been made clear, it ideally allows him to merge with a victim's body and destroy them from the inside, thus destroying their internal body. However, doing so seems to make him vulnerable to damage.

Utsusu (写す, "imitate/copy"): Azashiro is capable of copying his mouth and hands several times over, among other body parts, in several different locations at once. Doing so allows him to utilize hundreds of high-level Kidō, such as Ittō Kasō and Kurohitsugi, at the exact same time, allowing him to effortlessly overpower a large number of opponents and even eradicate a Captain-level opponent or stronger with overwhelming assaults of Kidō.

Don't know if Accelerator could. Hypothetically Azashiro could become the vectors. Well, possibly he could. But he can merge with anything including the atmosphere and ground. I don't think Accel is hax enough to get a win even assuming his vectors protect him from everything.

GET backers

No one you named aside from the Ginyu members can beat him. Their speed is irrelevant when he can teleport and have unlimited or at least numerous bodies. He can merge with them or anything he chooses, rendering most of their abilities useless. There are too many ways to counter them.

The limit is star level. I'd say Goku fits that criteria by scaling. But yeah if we include comic characters which I hadn't considered, then the list is a lot bigger. Planet level is probably a better limitation.

Kumagawa, Eucliwood, and any DBZ character over Freiza's level could beat this guy. The first two because of hax, and the third because of pure blitz. The trick with guys like this is to take them out before they can start using their extremely hax abilities.
